warning system cannot function reliably.
Only restart th
etyrep ressure loss warning
system when the defective whee lhas been
replaced with anew wheel. MOExtended tyres (tyres with run-flat
characteristics)
MOExtended tyres (tyres with run-flat char-
acteristics) allow you to continue driving the
vehicl eeven when one or more tyres lose all
air pressure.
MOExtended tyres may only be usedinc on-
junction with the activated tyre pressure loss
warning system or with the tyre pressure
monitor.
The maximu mpermissible distanc ewhich
can be driven in run-flat mode depends on the
load in the vehicle. It is 80 km if the vehicle
is partially laden and 30 km if fully laden.
The maximum permissible distanc ewhich
can be driven in run-flat mode is counted from
the momen tthe tyre pressure loss warning
appears in the multifunction display.
You must not exceed amaximum speed of
80 km/h. G
WARNING
The handling characteristics of your vehicle
deteriorate in run-flat mode, for example:
R when cornering
R when braking
R when accelerating rapidly
Adapt your driving style accordingly and avoid
sudden changes in direction and sudden
acceleration, as well as driving over obstacles
(i.e. kerbs, potholes), and driving off-road.
This is particularly the case when the vehicle
is heavily laden.
The maximum permissible distance that can
be driven in run-flat mode depends to alarge
extentont he loads placed on the vehicle. It
can be shorter due to high speeds, aheavy
load, sudden changes in direction, the road
surface condition, outside temperature, etc., or further if you drive carefully and conserva-
tively.
Do not continue to drive in run-flat mode if:
R you hear banging noises.
R the vehicle starts to shake.
R you see smoke and smell rubber.
R ESP ®
is intervening constantly.
R there are tears in the sidewalls of the tyre.
After driving in run-flat mode, you must have
the wheel(s) checked for damage at aquali-
fied specialist workshop which has the nec-
essary specialist knowledge and tools to carry
out the work required. The faulty tyre must be
replaced in every case.
Mercedes-Ben zrecommends that you use a
Mercedes-Benz Service Centr efor this pur-
pose. In particular, work relevant to safety or
on safety-related systems must be carried out
at aq ualified specialist workshop.
i When replacing one or all tyres, make
sure that you only use tyres marked
MOExtended and of the specified size for
the vehicle.
i Vehicles with MOExtended tyres are not
equipped with aTIREFI Tkit at the factory.
It is therefore recommended that you addi-
tionally equip your vehicle with aTIREFI Tkit
if you fit tyres that do not feature run-flat
properties, e.g. winter tyres. ATIREFI Tkit
can be obtained from aMercedes-Benz
Service Centre. Battery

mum possible service life, it must alway sbe
